You can't. Interrupt is happened independently from your main code. When
interrupt happens, it interrupts the execution flow, it suspends whatever
your main code is doing, and starts executing the code at the interrupt
vector (depending on your PIC that interrupt vector can be in different
places). It is your responsibility to write an interrupt handler, or
Interrupt Service Routine (ISR). Previously I put an example how it is
done. Within the interrupt handler you set a flag or increment a counter
which you can check in your main code... So for example:

         incf COUNT1, f
>          movlw  .10        ;Compare count to 100 decimal
>          subwf COUNT1, W        ;Store the result back in
>          btfss STATUS, C        ;Is the result 0, skip if no

This is pretty much you do, except you do not need to increment COUNT1 in
here -- you do that in the interrupt handler... Here you only check if that
reached 10 or not...

Does it make any sense?
